Butte F Fine Particulate M Matter (PM2 M2.5) P Plan anning Presentation to: Mat-Su Borough Assembly Meeting COMMISSIONER HARTIG & D E N I S E KO C H , D I R EC TO R , A I R Q UA L I T Y J U N E 7 , 2 0 1 6 1
Purpose se o of the P e Prese sentati tion • Goal is to protect Human Health • Air Monitoring is showing unhealthy levels of fine particulate matter • Wood burning sources • Need for immediate action • Local solutions • Collaboration with DEC’s Air Quality Program 2
Par articulate M e Matter er (PM) Hair cross section (70 µm) • A complex mixture of extremely small particles and liquid droplets. • PM 10 vs PM 2.5 Source: M. Lipsett, California Office of Environmental Health Hazard Assessment 3
Par article P Pol ollution on a and Public Heal Health • Health effects associated with exposure to fine particles include: • Premature death in people with heart and lung disease • Changes in heart rate variability; Irregular heartbeat; Non-fatal heart attacks • Increased hospital admissions and emergency room visits • Increased respiratory symptoms (coughing, wheezing and shortness of breath) • Lung function changes in children and older adults 4
Fine e Par artic icula late M Matter Sour urce ces ( (PM PM 2. 2.5 ) • Fine particulates are typically formed as a result of fuel combustion • Wood-fired heating devices • Burning construction debris or trash (burn barrels) • Land clearing 5
Fac actor ors That C Contribute t e to Air P Pol ollution on • Topography • Are you in a low spot? • Where are your neighbors’ homes in relation to your chimney? • Stagnant air conditions • Little or no wind to disperse smoke • Temperature inversions that trap smoke near the ground • Combustion sources • Wood heaters • Slash burning 6
PM 2. 2.5 Monitor oring • Year-round mandatory monitoring for PM 2.5 in Butte since Dec 1998 • Year-round monitoring in Palmer since 2011 • Public can access real time air monitoring data: ◦ http://dec.alaska.gov/Applications/Air/airtoolsweb/Aq/ 7
Mon onit itor orin ing • Butte monitor getting close to violating the national PM 2.5 standard • If Butte has >6 days over 29.1 µg/m 3 , the 2016 DV will exceed federal standards 98 th Percentile PM 2.5 2013 2014 2015 Design Value Not in Attainment* 24-hr Average Concentration, µg/m 3 27.9 39.5 37.9 35.1 35.5 *Compliance with the 24-hr PM 2.5 NAAQS is determined using three years of air monitoring data. The design value is an average of 98th percentile 24-hr average PM 2.5 concentrations over three years. • Palmer monitor shows lower concentrations (2015 design value of 10 µg/m 3 ) 8
Butt tte P PM 2. 2.5 Monitor oring: g: C Conseq equences es 2016 Monitoring values stay below 29.1 µg/m 3 : • Three year design value for 2016 will indicate Butte is in attainment • Continue to work to stay below standard for 2017 9
Butt tte P PM 2. 2.5 Monitor oring: g: C Conseq equences es 2016 Monitoring values are above 29.1 µg/m 3 : • Three year design value for 2016 will indicate Butte is in nonattainment • EPA could request State to submit recommendations for formal designations • EPA currently reviewing the 24-hour PM 2.5 standard and could issue a finding within the year 10
Conseq equences o of Nonattainment Formal designation by EPA as a nonattainment area triggers a wide range of expensive requirements that result in an Air Quality Plan that must be submitted within 3 years. • Failure to plan or submit required items results in federal sanction clocks. The sanctions include items such as 2:1 industrial offsets and a restriction in the use of federal highway money. • All federally funded projects (road or other types) must meet conformity in order to get funded • Once an area meets attainment, must maintain attainment for 20 years • Requirements for ordinances and regulations that are enforceable (voluntary measures alone will not be enough) • Plan must be able to demonstrate area can meet attainment • Clean Air Act allows citizen lawsuits for failure to implement a plan 11
Pot otentia ial C Con ontrol M l Measures Locally selected and implemented control measures have best chance of success. Ideas from other communities: • Promote or require the installation of cleaner burning wood heaters Device change out programs • • Promote or require the selling and burning seasoned, dry wood Moisture Disclosure Program (current State voluntary program) • Registered wood seller • Community drying lots or kiln • Loan out moisture meters • Issue firewood gathering permit to recently burned areas • • Pair air advisories with messaging (use alternative source of heat, burn dry wood) • Create a special purpose district with focused control measures Local burn approvals • • If in nonattainment, voluntary measures not sufficient 12
What C t Can R Resi esidents Do ts Do to Red educe Wood S Smok oke? • Better insulate and weatherize homes to reduce heating demands • Select a clean burning heating device sized appropriately to the space • Follow the manufacturer’s operating recommendations • Maintain wood heater and chimney • Only burn clean, dry wood in a wood stove • Check the moisture content of your wood – aim for 20% • Don’t let your fire smolder • http://burnwise.alaska.gov/ 13
Action on I Is N Nec ecessary t y to P Preven ent Nonat attainment How do we work together to engage community and explore options? • Public Education • Road side signs when entering/exiting Butte • Distribute materials through woodstove dealers, wood sellers, mail outs, etc. • Education on local weather patterns • Other ideas? • Local outdoor open burn ordinances • Incentive programs – device change outs, fuel switching • Enhance dry firewood options – energy logs • Conditions on slash burning/land clearing 14
Sugges ested ed N Next S Steps • Finalize Memorandum of Understanding – Clearly identify roles and responsibilities between DEC and Mat-Su Borough • Mat-Su Borough would have primary responsibility for preventing nonattainment – Local community best suited to tailor options and solutions • DEC involvement would increase if area becomes nonattainment 15
